【分析】
解题思路:先明确方框内词汇的词义与词性,再逐句分析句意,结合语法规则(如名词单复数、词性匹配)选择合适词汇并变形:1. 结合“擅长数学”选“数字”,用复数;2. 结合“解决数学问题”选“问题”,用复数;3. 结合“成为”选职业类名词,用单数;4. 结合“电影”选形容词;5. 结合“演奏两种”选乐器类名词,用复数;6. 结合“妈妈是”选职业类名词,用单数;7. 结合“充满”选不可数名词;8. 结合“在我们的”选固定搭配中的名词。
【解析】
1. 句意:彬彬擅长数字,所以最喜欢的科目是数学。be good with后接名词,此处表泛指“数字”,用number的复数形式numbers。
2. 句意:我们在课堂上学习解决数学问题。maths后接可数名词,problem用复数表一类,故填problems。
3. 句意:托尼未来想成为一名科学家。a后接单数可数名词,结合语境选scientist。
4. 句意:这部电影极好,我们都喜欢。be动词后接形容词作表语,excellent符合语境。
5. 句意:我会演奏两种乐器。two kinds of后接可数名词复数,instrument变复数instruments。
6. 句意:我的妈妈是一名好歌手。a后接单数可数名词,结合语境选singer。
7. 句意:这个故事充满魔法。be full of后接不可数名词,magic用原形。
8. 句意:中文在我们的生活中真的有用。in one's life是固定搭配,life用原形。
